The temperature was recorded at several times during the day. Function T gives the temperature in degrees Fahrenheit, N hours since midnight.
For each time interval, decide if the
average rate of change is positive,
negative, or zero.
a. From n=1 to n = 5
b. From n = 5 to n= 7
c. From n = 10 ton = 20
d. From n = 15 to n = 18
e. From n = 20 to n= 24

Find a parametrization for the curve「and determine the work done on a particle moving along γ in r3 through the force field f: r^3--r^3'where f(x,y,z) = (1,-x,z) and (a) im (γ) is the line segment from (0,0,0) to (1,2,1) (b) im (γ) is the polygonal curve with successive vertices (1,0,0), (0,1,1), and (2,2,2) (c) im (γ) is the unit circle in the plane z = 1 with center (0,0,1) beginning and ending at (1,0,1), and starting towards (0,1,1)
